Description

This application claims the benefit of U.S. Provisional Application No. 60/137,498, filed Jun. 4, 1999.

BACKGROUND OF THE INVENTION

Traditional deer feeds and attractants, such as corn and salt, are not optimal for deer's health. Regulations have been enacted, such as those adopted by the Texas A&M Animal Health Divisions, concerning the use of feed grains contaminated by aflatoxins.

Needs exist for deer feeds and attractants that are beneficial to deer and herds.

SUMMARY OF THE INVENTION

The present invention is for deer attractant and feed comprising mostly of stabilized rice bran.

Briefly, the present invention provides deer attractant and feed comprising stabilized rice bran and calcium carbonate. Limestone is added to the rice during the milling process. A byproduct residue from the milling process is rice bran and a small amount of pulverized limestone. Rice bran is a byproduct of rice milling that contains the seed coat, a fraction of the grain removed in milling, and the germ. Rice bran is a source of Vitamin B₁, Thiamine, which is found in animal organ tissues and functions in the body as a carboxylase, which is essential for conversion of carbohydrate to fat. The rice bran, preferably, is sieved for purity and is heated, cooked and extruded, resulting in stabilized rice bran flakes. The extrusion process destroys lipase activity and reduces the free fatty acid content to under 4%. The product contains about 12.5% or more protein, and about a 2:1 ratio of calcium (between about 3.25-4.25%) to phosphorous (minimum of 1.75%). The naturally occurring Vitamin B₁, Thiamine, aids in converting carbohydrates from browsing into fat as stored energy. The resulting attractant and feed promote deer health and growth, and the growth of antlers as well. The attractant promotes stronger does and bucks, which promotes healthier, better offspring. The deer feed may be spread out in the wild for deer to eat to cause herd distribution throughout resource areas and away from crops and gardens.

Rice bran is the outer brown layer of the rice kernel that is removed during the milling process, which generates the familiar white rice. Attached is a diagram of the rice kernel and its parts. The bran portion is one of the most nutritious parts of the rice kernel. The process of removing the bran layer from the kernel includes the addition of ground limestone, the powders remain as a source of calcium. The raw rice bran is taken as soon as it is removed from the kernel. The product is sieved in order to get to the purest parts of the rice bran. That aids in raising the fat levels. At that point, the bran must be stabilized. The rice bran is quickly brought to the heating, cooking and pressure extruding stabilizer. This must be done as quickly as possible to meet the standard definition of stabilized rice bran, which mandates that free fatty acids (FFA) be under 4%. The resultant stabilized bran flakes are cooled in a cooling system before packaging. The resultant product is packaged and sold as a deer attractant and feed.

There is no stabilized rice bran being sold in the deer attractant/feed/supplement market. Virtually all unstabilized rice bran goes into feed production for poultry and livestock. There is also a rapidly growing market for stabilized rice bran for the equine feed/supplement market.

The stabilized rice bran for the deer market has the following analysis:


		Preferred

Crude protein	12.5%	minimum
Crude fat	20.0%	minimum
Crude fiber	13.0%	maximum
Calcium	3.25%	minimum
Calcium	4.25%	maximum
Phosphorous	1.75%	minimum
Free fatty acids	4.0%	maximum

Because of the balanced nutritional analysis and the addition of calcium carbonate to the feed, the product aids in promoting overall deer growth as well as bone growth in bucks. Preferably, the calcium to phosphorous ratio is about 2:1.

The new product promotes wild herd management by attracting strong and healthy bucks and does into deer management areas.

Rice bran was originally developed as a commercial animal feed source. Through research and development, the present invention was found to be a unique food source for deer. Testing has shown huge successes in antler development, soft tissue development, hair coat and general overall animal health.

The present invention has a unique aroma that is attractive to deer and only contains about 2% or less salt. The present invention has only minute traces of aflatoxins and very low concentrations of salt (about 2% or less). This makes the present invention a very unique product, not only for deer but also for other wildlife that are susceptible to aflatoxins.

The present invention is unique to the stabilized rice bran market in that ground limestone is used as a milling agent in the removal of raw bran from the grain. The milling agent, in turn, provides the present invention with a balanced calcium to phosphorous ratio. A balanced calcium to phosphorous ratio is essential for organ and bone development in deer.

By controlling the free fatty acid to a very low level, the feed of the present invention is prevented from going through any chemical changes while being stored thereby providing an all natural product to the market.

The U.S. Rice Industry and the American Medical Association have done research showing that the use of rice bran leads to a lowering of bad cholesterol levels. The high fat content of the present invention makes the product a high-energy food source that is essential for survival of wintering deer herds.

These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the claims and the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is for deer feed comprising mostly of stabilized rice bran. Limestone is added to the rice bran during the milling process. The residue from this process, rice bran and a small amount of pulverized limestone, is then cooked in an extruder, resulting in stabilized rice bran. The extrusion process destroys lipase activity and reduces the free fatty acid content to under 4%. The product contains about 12.5% or more protein, and about a 2:1 ratio of calcium (between about 3.25-4.25%) to phosphorous (minimum of 1.75%). The resulting feed not only promotes deer growth, but promotes the growth of antlers as well. The deer feed may be spread out in the wild for deer to eat.

As shown in FIGS. 1 and 2, rice bran 3 is the outer brown layer of the rice kernel 1 that is removed during the milling process, which also removes the outer hull 5 and the germ or embryo 4 from the rice kernel 1. This process generates the familiar white rice 7. The bran portion 3 is one of the most nutritious parts of the rice kernel 1. The process of removing the bran layer 3 from the kernel 1 includes the addition of ground limestone, which is a source of calcium.

As shown in FIG. 3, raw rice bran 11 and residual limestone fines are processed as soon as they are removed from the rice kernel's endosperm. A belt 13 removes the bran and residual limestone fines from the milling machine. The raw rice bran 11 and fines are brought by the belt 11 to a sieving table 14. There the product is sieved by a reciprocating screen to get to the purest parts 15 of the rice bran. The sieving aids in raising the fat levels of the resulting product. The pure rice bran 15 and limestone fines are dropped to an auger 17 and are fed to an extruder 19 where the product is rapidly heated and cooked by high pressure steam and thereby stabilized. Preferred stabilizing equipment is supplied by Insta-Pro. The heated rice bran is compressed and then extruded. The flakes of the stabilized rice bran 21 are then quickly transferred by a belt 23 through dry air to a low temperature cooling system 25. The cooling system rapidly drops the temperature of the flakes, removes residual moisture, and discharges the flakes at ambient temperature. The cooled, stabilized rice bran flakes 21 exit the cooler 25 on a belt 27 to be packaged. The rice bran must be moved as quickly as possible to the extruder 19 and cooler 25 in order to meet the standard definition of stabilized rice bran, which mandates that free fatty acids (FFA) be under 4%.

No calcium fortified stabilized rice bran 21 has been or is being sold in the deer feed/supplement market. Virtually all unstabilized rice bran goes into feed production for poultry and livestock. There is also a rapidly growing market for stabilized rice bran for equine feed/supplement.

An example of the stabilized rice bran flakes 21 for the deer feed market has the following analysis:


	Crude protein (min.)	12.5%
	Crude fat (min.)	20.0%
	Crude fiber (max.)	13.0%
	Calcium (max.)	4.25%
	Calcium (min.)	3.25%
	Phosphorous (min.)	1.75%
	Free fatty acids (max.)	4.00%

Because of the balanced nutritional analysis and the addition of calcium to the feed, the product aids in promoting strong organs, fat production, overall deer growth and bone growth, as well as antler growth in bucks.

Deer are ruminant mammals of the family Cervide that browse on bushes, twigs and branches of deciduous evergreen and semi-evergreen shrubs, bushes and trees, and as a result take in copious carbohydrates. Surprisingly, the Thiamine, Vitamin B₁, in the new deer attractant and feed assists in converting the carbohydrates to stored energy in the form of body fat and builds strong organ tissues, while the high oil/fat content of the rice bran flakes contributes to the nutrition and coats of the animals, promoting health. The powdered calcium carbonate in the feed provides bone growth and density and antler growth, and the calcium-phosphate balance contributes to muscle development, which together make strong, healthy, large deer.

While the invention has been described with reference to specific embodiments, modifications and variations of the invention may be constructed without departing from the scope of the invention, which is defined in the following claims.
